LUBRlCATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 681,615, dated August27, 1901. Application filed January 17, 1901. Serial No. 43,616. (Nomodel.)

To all whom it may concern.-

Be it known that I,J OHN W. BowERBANIga citizen of the United States,and a resident of Jersey Gity,in the county of Hudson and State of NewJersey, have invented a new and Improved Lubricating Device, of whichthe following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved lubricatingdevice which is simple and durable in construction,very effective inoperation, and arranged to permit of using all kinds of lubricants,notably greases that harden when cool, and to economically feed thedesired amount of lubricant necessary for proper lubrication only duringthe time the part to be lubricated is running.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented. in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a longitudinal sectional elevation of the improvementasapplied to a journal. Fig. 2 is a transverse section of the same on theline 2 2 in Fig. 1, and Fig. 3 is an enlarged longitudinal sectionalelevation of one of the roller-disks.

The improved lubricating device consists, essentially, of a receptacleA, adapted to contain the lubricant and provided at its upper end with acover B and at its lower end with segmental flanges O,adapted to rest ona bearing D for the journalE to be lubricated. In the ends of thereceptacle A are arranged vertically-disposed bearings F, and similarbearings F are located at the middle of the receptacle A, and in saidbearings are journaled the ends of shafts G, each carrying a pluralityof disk rollers H, extending within the receptacle A and through slotsA,formed transversely in the concave bottom A of the receptacle A. Aperforate hopper I is set in the upper portion of the receptacle A overeach shaft G, the ends of the hopper being between the disk rollers IIand the lower end of the hopper being above the shaft G, as is plainlyindicated in Fig. 1.

The grease or other lubricant is placed in the hoppers I, and when thejournal E is rotating then the heat emanating therefrom causes thegrease in the hoppers I to melt and flow upon the bottom A of thereceptacle and upon the faces of the disk rollers H, so that the lattercarry the liquid lubricant upon the peripheral surface of the journal Eas the said roller-disks and their shafts are rotated by the rotatingjournal E. Now it is evident that when the hoppers I are filled withgrease and the journal E is not running then the grease hardens, andconsequently is held in the hoppers and the bottom of the receptacleWithout danger of flowing to the roller-disks and the transverse slots Adown upon the journal.

As illustrated in Figs. 1 and 2, the ends of the perforate hoppers areextended and rest on the bottom A of the receptacle, the proj ectingportions of the ends being slotted for the passage of the ends G. By thearrangement describedahe perforate hoppers are supported within thecasing without further supporting devices or fastening means.

As shown in Fig. 3, each of the roller-disks H is preferably made of anumber of disks fastened together, the disks being of diderentmaterialthat is, the outer disks being preferably of a softer materialthan the middle disk extending between the outer disks. For instance,the outer disks are preferably made of copper, while the middle disk ismade of steel, and in a similar manner the shaft G has a central core ofsteel and a sleeve of copper extending from one disk roller to theother, as indicated in Fig. 3. By the arrangement described the heat ofthe journal E is quickly transmitted by the roller-disks and its shaftto the lubricant, so that the latter quickly melts when the journal E isrunning.

It is understood that the bearings F F are so arranged that theroller-disks rest by their own weights on the peripheral surface of thejournal Ethat is, the ends of the shafts are free to move up or down insaid bearingsbut the latter hold the shafts against transverse movement.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A lubricator, comprising a receptacle forcontaining a lubricant, and provided in its bottom with a transverseslot, and a rollerdisk loosely journaled in said receptacle andextending through said slot to engage the peripheral surface of the partto be lubricated, substantially as shown and described.

2. A lubricator, comprising a receptacle for containing a lubricant andhaving transverse slots in its bottom, roller-disks extending throughsaid slots to contact with the periphery of the part to be lubricated,and bearings in the receptacle for said roller-disks, to allow thelatter to rest by their own weight on the part to be lubricated, and tohold the roller-disk against transverse movement, as set forth.

3. A lubricator, comprising a receptacle having a concave bottom withtransverse slots, roller-disks extending through the slots to contactwith the part to be lubricated, a shaft connecting the roller-disks witheach other, and bearings in the receptacle for said shaft, as set forth.

4. A lubricator, comprising a receptacle having a concave bottom withtransverse slots, a perforate hopper set in said receptacle,roller-disks extending through said slots, a shaft connecting theroller-disks with each other, and bearings in the receptacle for theshaft to turn in, the part of the shaft extending between theroller-disks being below the lower ends of said perforate hopper, as setforth.

5. A lubricator havinga receptacle for containing a lubricant, andprovided with transverse slots in its bottom, roller-disks extendingthrough the slots, to contact with the part to be lubricated, and ashaft connecting the roller-disks with each other, said rollerdisks andshaft being made of different metals, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
